BALI NG-PR ESS- Specification of Letters Patent.

Patented Jury 25, 1905.

Application filed March 9,1905. Serial NH. 249,233.

V art to which it appertains to make and use the same.

My invention relates to baling-presses, and more particularly to means for operating the plunger of the machine. I

The object of the,in vention is to provide a power adapted to be operated byone or more draft-animals, said power coacting with a toggle in such a manner as to produce two complete pressing operations to each rotation of the power-beam.

Another object is to dispense with the use of springs or like devices for the purpose of returning the plunger to its initial position subsequent to a pressing operation, such return movement being produced by the powerbeam.

With the above and other objects in view the invention consists of a press of any preferred construction havinga plunger arranged therein and connected in any suitable manner to one end of a toggle, the other end thereof being connected to a fixed pivot. A lever is fulcrumed adjacent the toggle and is secured to a beam to which one or more draft-animals are adapted to be secured,and this lever during the rotation thereof serves to extend the toggle each time the ends thereof contact with it. An extension is so arranged upon the toggle as to engage the lever during its rotation in such a manner as to retract or break the toggle, and thereby return the plunger connected to it to its original or initial position.

The invention also consists in further novel construction and combination of parts hereinafter more fully described and claimed.

In the accompanying drawings I have shown the preferred form of my invention.

In said drawings, Figure l is a perspective view of a baling-press having my improved power connected thereto. Fig. 2 is an enlarged plan view of the power and showing the operating-lever contacting with the toggle prior to extending the same. This view also illustrates in dotted lines the positions assumed by the parts when the lever is engaged by the toggle prior to the operation of breaking or retracting the same. Fig. 3 is a section on line 3 3, Fig. 2. Fig. 4 is a central vertical section through the body of the press and the plunger. Fig. 5 is a section on line 5 5, Fig. 4:; and Fig. 6 is a detail perspective view of the plunger.

Referring to the figures by numerals of reference, 1 and 2 are the top and bottom, respectively, of the body of the press, and crossstrips 3 are secured thereto and have their ends connected by means of rods 4:. Side walls 5 are arranged between the top and bottom at opposite sides of a feed-hopper 6, which is disposed upon the top 2. A bail 7 connects one end of the top and bottom of the press and extends across said top. The central portion of this bail is engaged by one end of a lever 8, which is fulcrumed between ears 9, secured upon the top 2. A weight 10 is adjustably connected to the lever 8 and is preferably supported therefrom by any one of a series of hooks 11. It will be understood that this weight causes the opposite end of lever 8 to press upward against the bail 7, thereby forcing the fulcrum of the lever downward and serving to press the top and bottom of the press toward each other. This action is permissible in view of the fact that no supports are provided for the top at points adjoining the end to which the lever 8 is connected.

A plunger comprising a base 12, a head 13, and side flanges 14: is adapted to reciprocate within the press between the walls 5 thereof, and in order to reduce friction this plunger has rollers 15, which travel upon the bottom of the press. A stem 16 projects from the base 12 and is pivoted to a rod 17, slidably mounted upon a suitable bed 18. That portion of the bed upon which the rod is mounted is preferably covered by a'shield or guard 19, whereby an animal or animals employed for operating the press may pass thereover without injuring the rod.

The bed 18 may be of any desired length, and to its outer end is pivoted a strip 20, having one member 21 of a toggle rigidly connected to the central portion thereof and extending at right angles therefrom. This member is pivoted to the second member 22 of the toggle, which in turn is pivotally connected to the rod 17 Member 21 is recessed in one edge, as shown at 23, and partly overlapping this recess is a block 24, which is for a purpose hereinafter more fully described. A lever 25 is centrally fulcrumed at a point 'tion of the arrow in Fig. 1. .lever 25 will therefore be swung against the to the bed 18 it will cause the members of the toggle to aline, and ears 27 project from the ends of thelever and are adapted to overlap the member 21 when said lever is in contact with the toggle.

Apower-beam 28 is connected in any suitable manner to the lever 25 and is provided with means whereby one or more draft-animals may be secured to it.

In using the mechanism herein described the beam 28 is caused to rotate in the direc- One end of the member 21 of the toggle, causing said memher to move upon 1ts pivot 29 and pressing the member 22 forward until the lever 25 assumes a position substantially at right angles to the bed 18, as shown by dotted lines in Fig. 2. As beam 28 continues to rotate the advancing end of the lever 25 will move into the recess 23 and abut against the block 24. Said block-will be Forced out of the path of the lever as said lever rotates, and therefore the toggle will be moved backward to its normal" or broken position, as shown by full lines in Fig- 2, and the plunger will be retracted. The material to be pressed may be fed into the press through the hopper 6 and between the plunger and adividing-block (not shown) and which is adapted to be placed between the weighted portions of the top and bottom of the press. Each rotation of the powerbeam 22 will, as is obvious, produce two forward movements of the plunger, and any material fed through the hopper 6 will therefore be quickly compressed against the dividing-block within the machine. If for any reason said block should become wedged or otherwise held against movement during the operation of the power, the weighted beam 8 will allow a certain amount of expansion in the compression chamber, and thereby release the block and prevent any of the parts of the power from breaking.

By providing a power such as herein clescribed it will be noted that I obviate the use of springs, weights, or 'other like devices for returning the plunger to its initial position, and, moreover, by the utilization of a toggle and a lever without any connecting devices whatsoever I am enabled to produce two distinct compressing operations during one revolution of the lever.

It will be seen that the power is very simple and inexpensive and is of such a nature as 1. A power mechanism of the character described comprising a pivoted strip, a toggle having a movable end and rigidly connected at its other end to said strip, a rotatable opcrating-lever, the ends of which are adapted to successively contact with and extend the toggle and means upon the toggle for successively engaging the ends of the lever to retract the toggle.

2. A power of the character described comprising a pivoted strip, a toggle having a movable end and rigidly connected at its other end to the strip at a point removed from the pivot thereof, a rotatable operating-lever having ends adapted to successively contact with and extend the toggle and means upon the toggle for successively engaging the ends of the lever during the rotation thereof.

3. A power of the character described comprising apivoted strip, a toggle having a movable end and its other end rigidly connected to the strip at a point removed from its pivot, a rotatable operating-lever having ends adapted to successively bear upon and extend the toggle and a block upon the toggle in the path of and adapted to be engaged by the ends of the lever.

' 4:- In abaling-press, the combination with an expansiblecompression-chamber and means for normally holding said chamber against expansion; of a plunger slidably mounted within the cbmpression-chamber, a pivoted strip, a toggle rigidly connected at one end to said strip and at its opposite end to the plunger, a rotatable operating-lever having ends adapted to successively contact with and extend the toggle and an engaging device upon the toggle for successively engaging the ends of the lever during the rotation thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
